How To Update LG Optimus 3D P920 with Ice Cream Sandwich Android 4.0 Firmware

Procedure to update Ice Cream Sandwich 4.0 on LG Optimus 3D:

  • First up you need to download the Ice Cream Sandwich 4.0 Firmware Zip to your computer. Once it’s downloaded, you will now need to proceed to connect the phone to the computer using the USB cable which you got at the time of purchase.
  • So, once you are done with the downloading, you need to copy this downloaded zip file as it to your phone without modifying or renaming the file. Once you copy the same, you now need to download the ROM Manager application in your phone.
  • The ROM Manager can be installed from the Android Market Place. Now, once you downloaded and installed the ROM Manager application, you need to open the same and then select the option of “Flash Clock Work Mod Recovery” to flash the same.
  • Once you are done with this, you now need to create a backup of your current ROM which you can do by selecting the option of “Backup Current ROM” in the ROM Manager so that you can then revert back to the Stock original version just in case if you face any issues with the new Ice Cream Sandwich ROM as its in the beta stage.

ROM Manager backup Restore

  • After this select the option of “Install ROM from SD Card” and then you will have to choose the zip file of “IceCREAMSandwich4.0_for_LGOptimus3D_KingROM” after which the process of the firmware update will be commencing.
  • After a period of around 5 – 8 minutes, the firmware update process will be finished and then you will see that the device will be restarted on its own, if not then you need to select “++++ Go Back ++++” to get back to the main menu and then choose to “reboot system now” to restart the phone.
  • Just in case if you are facing issues like the Force Close errors then you need to select the options Wipe data/factory reset, Wipe Cache partition and then choose reboot system now to restart the phone and to enjoy this all new firmware.

Do let us know just in case if you face any issues in the comments section below as we will try our level best to help you. So, in this way you have easily updated your LG Optimus 3D smart phone with the latest version of Android Ice Cream Sandwich 4.0 version.

    Can i have the download link for the firmware??… it not working..!!!

  • Cynagen

    Zip is corrupted, and don’t tell me to redownload cause I have a business connection with 0 issues with everything else on the web, so frankly this makes me weary of loading this up onto my phone. And I so want ICS damnit.

    • http://www.androidadvices.com/author/neal Pradeep Neela

      you can download the same again or from the source link below

  • IceMan_DX

    This is not the offical ICS OS Fools but a Rom !!!! Now your fucked over and cant even have the phone repaired under warrantie !!!!

  • Claudia

    OMG i just put it on my phone, n now it has random flashing boxes and i can’t click on anything, Can any one please help? thanks

  • Jordane Quissanga

    I did all steps mencioned here, step by step, or from begin to the end. The diference that I saw is all pictures posted on this website is very very diferent from the phone, I do not why.

    I agree with Vortecduramax, Bara 93, tyler wewsecv, almost said the same thing, I just don’t know what is wrong with KING 3D ROM, even I cannot find out its official website. Now, my phone is broken ’cause of it. It does not power on anymore.

    I’ll send it to Lisbon, Portugal, to be repaired for free without any fee/charge/fare.

    I just wish much luck for who has it on phone and it runs normally, my best.

    • Yogesh Patel

      First thing disable any Voodoo tools on your phone if any.

      Follow the steps carefully in page 2, if you miss single step it will not be updated.

      Thanks You!

  • Not Impressed

    Can’t believe Android Advices would fall for this rom being ICS.. meh, trashes your credibility guys….

    Is a Froyo Rom with custom themes.

  • Charliehowlett

    So…what should I do if my LG Optimus 3D P920 has randomly said it wanted to >>UPDATE<< (Not mentioning software or firmware) and won't let me do anything? I've tried taking the SIM out and turning it back on and off, but nothing seems to work=/ ANY IDEAS PLEASE!!! If it's broken I'm screwed=//

    • http://twitter.com/pradeepneela Pradeep Neela

      since its an official update which you tried to update with and it failed, you need to contact the LG Service centre for the same!

  • http://www.wiki.org ElNinyo

    Hi, nothing..my LG 3D doesn’t install THIS ROM so yesterday evening i try to install the famous KING ROM 3D 2.2..and it’s OK !

    There is anyone that try this (and explain us if this started immediately or what to do) ?

  • isokpan efe

    how can I upgrade lg p970? or can I use this?

    • http://twitter.com/pradeepneela NeaL Pradeep

      no, p70 is a different model you cannot apply this procedure!

  • Andrea

    nothing to do, neither with data+cache & dalvik clean ! :o(

    everything appear to be ok at restart (ok..ok..) then my phone reboot immediately (i think with an error): where can i find LOG file?

    • http://twitter.com/pradeepneela NeaL Pradeep

      you cannot find the log file!

      • Andrea

        o no…shit ! So i can’t find where is the problem ! :(

        What can i do ?

    • Andrea

      i try another time following the procedure : everything appear to go but after few second after my LG 3D “unzip” the ZIP file the phone reboot (i think with an error…)
      Can it depend from my “Vodafone” LG 3D (but with rooted + CWM) ?

      What can i do ?

      • http://twitter.com/pradeepneela NeaL Pradeep

        its not recommended to update the n/w locked devices!

        • Andrea

          Ciao, mine is unlocked : my network provider now is H3G (3 italia)

        • Andrea

          Ciao NeaL, you appear to be good informed : my LG 3D was Vodafone but i buy it unlocked (Now my network provider now is H3G (3 italia) : what can i do ?

          Its original firmware is really slow, is the worst i ever found…and doesn’t exist the famous very good MIUI for it : i think this is my only chance for now ! =:| :o)

          • http://twitter.com/pradeepneela NeaL Pradeep

            you can apply this, let us know if you face any issues!
